Dynamic routing name

In this article, I am going to show you an easy way to set up Angular Dynamic Routing using Angular Router feature.

Step 1: Setup Project

Create Project using following Angular CLI command.
ng new article-routing

Step 2: Create Component

Open that project and create component using follwing command. ( if your using VS code use ctrl+` to open and close command prompt ).
ng g c article

Step 3: Setup Dyanamic Route

Open app-routing.module.ts file and add path name and component in “Routes” Array (app-routing.module.ts file created automatically in project when create project).
const routes: Routes = [
{  
  path:'',
  component: ArticleComponent
},
{
  path: 'article',
  component: ArticleComponent,
  children:[
             {
               path:'article/:type', //:type is dynamic here
               component:ArticleComponent
             }
           ]}
];

Step 4: Import Router and create instance of Router in article Component

Open article.component.ts file and import Router and create instance of that.
import { Component, OnInit } from '@angular/core';
import { Router } from '@angular/router'; //import router@Component({
selector: 'app-article',
templateUrl: './article.component.html',
styleUrls: ['./article.component.css']
})export class ArticleComponent implements OnInit {
constructor(public router:Router) { }  //create instance
ngOnInit() {}
}

Step 5: Pass dynamically route type

open article.component.htmlfile and write following logic. On every button click dynamic type parameter is passed using routerLink. And added condition on every paragrap ( <p> tag).
<h2>Article</h2><button type="button" routerLink='/article/trending'> Trending</button>&nbsp;
<button type="button" routerLink='/article/politics'> Politics</button>&nbsp;
<button type="button" routerLink='/article/business'> Business</button>&nbsp;
<button type="button" routerLink='/article/social'> Social</button>&nbsp;
<button type="button" routerLink='/article/bollywoodHollywood'> Bollywood/Hollywood</button><p *ngIf='router.url.includes("trending")'>Your are in Trending Section</p>
<p *ngIf='router.url.includes("politics")'>Your are in Politics Section</p>
<p *ngIf='router.url.includes("business")'>Your are in Business Section</p>
<p *ngIf='router.url.includes("social")'>Your are in Social Section</p>
<p *ngIf='router.url.includes("bollywoodHollywood")'>Your are in Bollywood/Hollywood Section</p>
Now , serve the project using Angular CLI command
ng serve
Now you can see changes on button click. (if you are a begineer , after ng serve , project will serve on localhost:4200 which is default port of angular)

Understand Angular’s forRoot and forChild

  forRoot   /   forChild   is a pattern for singleton services that most of us know from routing. Routing is actually the main use case for it and as it is not commonly used outside of it, I wouldn’t be surprised if most Angular developers haven’t given it a second thought. However, as the official Angular documentation puts it: “Understanding how  forRoot()  works to make sure a service is a singleton will inform your development at a deeper level.” So let’s go. Providers & Injectors Angular comes with a dependency injection (DI) mechanism. When a component depends on a service, you don’t manually create an instance of the service. You  inject  the service and the dependency injection system takes care of providing an instance. import { Component, OnInit } from '@angular/core'; import { TestService } from 'src/app/services/test.service'; @Component({ selector: 'app-test', templateUrl: './test.component.html', styleUrls: ['./test.compon...

How to solve Puppeteer TimeoutError: Navigation timeout of 30000 ms exceeded

During the automation of multiple tasks on my job and personal projects, i decided to move on  Puppeteer  instead of the old school PhantomJS. One of the most usual problems with pages that contain a lot of content, because of the ads, images etc. is the load time, an exception is thrown (specifically the TimeoutError) after a page takes more than 30000ms (30 seconds) to load totally. To solve this problem, you will have 2 options, either to increase this timeout in the configuration or remove it at all. Personally, i prefer to remove the limit as i know that the pages that i work with will end up loading someday. In this article, i'll explain you briefly 2 ways to bypass this limitation. A. Globally on the tab The option that i prefer, as i browse multiple pages in the same tab, is to remove the timeout limit on the tab that i use to browse. For example, to remove the limit you should add: await page . setDefaultNavigationTimeout ( 0 ) ;  COPY SNIPPET The setDefaultNav...
